Review on Garmin GPSMAP 62 64 64s 64st Screen Protector (Pack of 4) - Akwox Tempered Glass Protective Film, 0.3mm 9H Hardness, Scratch-resistant, Compatible with GPSMAP 62 62s 62sc 62st 62stc 64 64s 64st GPS Devices by Michael Vargas

Installed on my Garmin Astro 430. Same unit as model 64 but with the addition of a dog for GPS tracking. The installation and installation kit works very well. The screen corresponds to the edge of the factory GPS screen. Everything seems fine, but here's the bad news. The edges are square cut (no chamfer). This makes them very prone to chipping. Hit something with the edge of the screen and it squeaks or chips fall off. I used up all my four pack and don't want to buy it again. Bevel the outside edge and this product will be perfect.
